How do you stop homegrown terrorism? After Monday night’s terror attack in the UK, it’s a question many are trying to answer.

“It’s extremely difficult to protect the country from an individual who’s intent on carrying out this type of attack,” Milton, said.

“When I started dealing with terrorism issues, we dealt with terrorist who wanted to put a bomb down, set the timer, and run away,” Milton said. “Here, we have a completely new set of people who are prepared to die for their cause. It’s very difficult to stop them.”

Milton works with Homeland Security and Bay Path in Longmeadow, teaching people how to spot signs of someone who may be radicalized, and more importantly, giving them the courage to report it.

“I absolutely guarantee there were people who surrounded this individual who knew that his behavior had changed,” Milton said. “People who had suspected he had been radicalized.”

Milton said in some cases, acts of violence could have been prevented, if the people around them had picked up on the signs and reported it.
